My new kitchen is a similar dimension to yours, but where you show your dining table, I have a love seat (our family room). I've attached a photo of the kitchen section for perspective. The stove wall is about 14 feet. What is the cabinetry you show between the windows? A pantry? Sorry, I can't see what's typed on your pics. You could also consider putting your wall of cabinetry and appliances against the window wall and turn the island to face the den. Personally, I would rather have the main kitchen sink under the 42" window. It's a great space. Good luck!

Here's an older thread on mixing overlay styles: http://ths.gardenweb.com/discussions/2693650/inset-uppers-with-full-overlay-lowers

I'm really liking the two tone look lately. I'm debating about it for my cabin's kitchen, so of course I had to search for some examples. Here are few I found. This one is my favorite! Here are a few from GW that did the wood fridge surround which I like. I'm not sure though if in a smaller kitchen whether or not it would be better for all the uppers to flow with the fridge surround??? Hopefully others will chime in. Here is one with white around fridge and oven stack. I like both! But I am leaning toward the wood surround myself. I really think it's more just personal preference though because both look nice. I would also consider how much natural light your kitchen has as that might make you lean toward white. If you could post pictures of your existing space that would help us give the best advice.

Oh, this isn't hard at all. I've retrofitted a few base cabinets with drawers like this. Granted, most had a face frame, so it was just taking off the existing (stupid) doors, adding drawer glides and drawer fronts. In the case below, I stuck a face frame on an existing overlay drawer cabinet, then made the drawer fronts out of pallets and a board I found in the mud, at a friend's farm. The 2nd photo shows this cabinet next to overlay cabinets. Because the new face frame brought it out 3/4", it was flush with the overlay cabinets giving them a pseudo-inset look. A couple cabinets I put a horizontal frame piece (rail? stile?) in with pocket hole screws, attached drawer glides and then drawer fronts. The picture below was when I was still fussing with overlay cabinets. These uppers were 42" tall, but I wanted the look of stacked cabinets. (This is before I had my OMG AHHH HAAAAAA moment that my true love in life, everlasting adoration, is beaded inset cabinets.) Anyway... You could easily put inset doors in these. THEN, On some kitchen cabinets I took frameless cabinets, put the whole darned face frame on and have butt doors (no vertical piece in between the doors) installed. On these last cabs, I actually took a 24" tall cabinet and stuck a 12" cab on top of it (=36") then put a face frame on the whole darned thing so it looks like a single cabinet. Turned out far cooler than my very vivid imagination could see! Inset, of course. Please ignore the crap in there. I had to use the cabinets in the meanwhile. The top 12" cab had a face frame, so the new one I built went on top. I left the center style as a door stop. Note the tiny edge at the top of the bottom space. That edge of the cabinet is its door stop. With doors in: Ok, I also took three, 3-drawer base cabinets. 36" + 24" + 36". I made a face frame that is 96" long with the 30" vertical pieces. When you take the actual cabinet face frames stuck together, those vertical pieces = 1.5". My new face frame had 3/4" pieces. The extra, original face frame underneath became drawer stops. The inset drawer front fit right in that face frame without fussing with how far in to go. (A drawer glide must be 7/8" inside the face frame for inset drawer fronts to fit nicely. Original 3 cabinets: This is a close up of the face frame over the existing cabinets. Note how the drawer glide is inset 7/8". Here's the face frame installed. I haven't put all the slab drawer fronts on at this point. (Anyone need a lot of overlay drawer fronts? I have about 20 of all sizes.) You wouldn't need to build a face frame AROUND an IKEA, frameless cabinet, but on top of the frameless cabinet. It would give you a 3/4" deeper cabinet. You wouldn't need an end piece between them, rather a simple 1x2 (so .75 x 1.5) piece between mine. The face frame screws hold it just fine. I realize as usual, this is one of my novels, but what you're imagining can be done rather easily and VERY inexpensively on so many levels.
